When it hits your skin it will impart a force. This force acts on a very small area (the paper is sharp) and consequently applies a very large pressure to the surface of the skin. This is easily sufficient to penetrate the skin and cut it.
The same argument applies when you strike your skin against a stationary sheet of paper.
